DRYING under the sun is the most common and traditional way of drying goods like rice and corn to maintain the dryness of these staple products, particularly in the Philippines.Although it is cheaper, it becomes a problem during rainy season. Every piece of rice wasted is equivalent to the perspiration and hardship of Filipino farmers but a lot of harvested products go to waste because of the old ways of drying. Now, there is an alternative method of drying rice, corn, mongo and other grain products. Inventor and entrepreneur Francisco 'Popoy' Pagayon, president of the Filipino Inventors Society Producers Cooperative (FISPC), takes pride in his invention of Portasol — a portable, stackable set of grains thermal drying trays, which can accommodate 150 kilos of palay per drying.The innovative Portasol was designed to provide and help farmers, rice and corn traders a more effec-tive and efficient technology to dry their grains and even for drying fish (daing).This multi-purpose drying equipment is made of aluminum thermal trays that can either be laid out on a flat surface or set up in a rack format in a backyard and does not require much space. Equipped with a net cover for use when installed in a rack format, it preserves heat and shield the crops from pests, rodents, bacteria and other contaminants.The use of portasol is three times better than the traditional way of drying harvested produce. This greatly helps farmers to avoid spoilage and to up the quality of the dried products.'This is the long overdue solution to the farmers' dilemma in finding an effective, efficient and 'safe' place for drying their produce. Paved roads and highways are for motor vehicles, so why use these for drying their yields?' the inventor said.
